Brake Controller Wiring on a 2005 Ford F-150 without a Tow Package
Question:
I have a 2005 F150 supercrew that did not come equiped from the factory with a tow package. I see that the pigtail for the trailer brake is under the dash, but Ive been told that the wires may not run to the back. I have a flat four on the rear bumper, but the wiring is integrated with the other rear electical wires at the back of the truck and not a separate plug like the illustration for an 03. I need to install a trailer brake controller and s seven plug connector. Where should I start and how is it done? Any suggestions would be great.

Expert Reply:
You will need part number 37185.
If you look at the Display picture, you will see 4 loose wires coming off of the adapter and a 4-pole connection. You will plug the 4-pole into your existing 4-pole. The White wire you will ground.
White: Ground
Blue: Brake
Black: Hot Lead - 12V power supply
Purple: Aux. - Reverse Lights etc.
Follow your 4-pole harness back until you run into another connection point (not quite as far as the rear tire).
